Auspex Posted December 13, 2009 Share Posted December 13, 2009 I had no luck with it on shark's teeth on the beach at Virginia's Calvert Fm. (Miocene). Tried it at night, with different frequencies.

Seldom Posted December 13, 2009 Share Posted December 13, 2009 But who would seriously hunt at night????? Never been to Texas hunting have you. Ask Dan the best fossils come out at night. Galveston Island 32 miles long 2 miles wide 134 bars 23 liquor stores any questions? Evolution is Chimp Change.

Bear Posted December 13, 2009 Share Posted December 13, 2009 Great way to find scorpions though, as they fluoresce quite well under UV. I use my UV flash to ID rocks though...fossils don't do anything under it. Link to comment Share on other sites More sharing options...

Hi Bear: Thanks for your observations... one thing to note Placoderms mentioned on another thread than he had some success with fish bone/armor lighting up under certain UV wavelengths .

Harry Pristis Posted December 14, 2009 Share Posted December 14, 2009 Has any one used a battery operated UV LED light source for Fossil Hunting? Tell us your experiences and applications in the fossil hunt. PL Posted 22 March 2009 - 03:05 PM I just bought a new toy. It's a 51 LED ultraviolet flashlight. A quick sweep of my fossils reveals that teeth from the Badlands flouresce nicely. With other fossils, it's hit and miss. Tampa Fm. agatized coral does flouresce. Butvar-76 and Glyptal flouresce. Repairs with epoxy and epoxy casts flouresce brightly. Casts made of polyester resin do not flouresce. That is, in the wave-length produced by these LEDs [395nm in the UVA spectrum]. Fossils from the phosphate at Aurora, NC, flouresce nicely. Anyone been there at night with a UV flashlight? 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

Today I just bought 2pc with 12 UV -LED flashlights from Ebay to explore flourscent effect on fossils... lots of fun. PL Link to comment Share on other sites More sharing options...

Guest Smilodon Posted December 14, 2009 Share Posted December 14, 2009 Just to expand, Almost all teeth from the Badlands fluoresce yellowish under long wave. Bones will sometimes fluoresce green and red under shortwave. Most Moroccan shark teeth fluoresce under long wave as do Chinese teeth. BUT, check out your fossils after you turn off the light. Some wil phosphoresce, that is, they light up AFTER you turn the light off. I have several specimens including a sabercat skull from China where the teeth do that. Really eerie, as you can imagine. It's Halloween 24/7 at Miller's Fossils. :startle: Link to comment Share on other sites More sharing options...
